I love training, but I think that I'm too strong right now. I kill every boss with ease. Lol. Should I stop or keep going? Are there really hard bosses in this game? Are there secret bosses that are harder then the main story bosses?

Cool! Do I have to press "new game or continue" to play those 2 new dungeons?

- Thanks =)

Continue from the Nox save point. Kill the Undying Dragon in the Door Left of the Red Stairs, Go to the Right Door and teleport back to the Landing Area. Go to the Coliseum in Tatroi, Go to the Door sealed with Light, Use the Darkness Ring to Unseal, Enter the....|CAVE OF THE SEVEN STARS||

Yes, you have to kill the last boss and save you game, and then reboot it. Kill the dragon in the left chamber before the final boss, then take the teleporter out from the right.

The second dungeon (Wandering Dungeon) is found in E.N. II. (Energy Nede 2?!) I think you have to talk to the guy who guards the Old Road to the Sanctuary. I haven't gotten into there yet but I'm pretty sure that's how.
